A tender heart is a wakeful, watchful heart. It watches against sin in the soul, sin in the family, sin in the calling, sin in spiritual duties and performances.
John BunyanFear, lest, by forgetting what you are by nature, you also forget the need that you have of continual pardon, support, and supplies from the Spirit of grace, and so grow proud of your own abilities, or of what you have received from God.
John Bunyan
